How to Seal Block Paving – Complete Process
If you want to learn how to seal block paving driveways, consider following the below step-by-step process.
Step 1 – Cleaning the Surface
The first and foremost step while sealing your block pavers is to clean them. Cleaning your block pavers or outdoor floor tiles is important to wash away all the dust and debris. Pressure wash the surface of your block pavers to remove algae, lichen, dirt, dust and weeds. If there are tough stains like oil and grease, consider removing them with quality oil stain remover. Once you’ve applied the stain remover, leave it to dry for around 2-3 hours. Once the surface is dried, sweep it with a stiff broom.
Step 2 – Sanding the Joints
Once the surface of your block pavers is completely dry, sanding the joints would be the next step in the process. Refill the joints between the pavers with jointing sand, as the existing sand would have washed out during the cleaning process. Now, brush a thin layer of jointing sand over the surface and sweep into the joints. Once the sand is consistent, you’re ready to seal your block pavers.
Step 3 – Preparation for Sealing the Block Pavers
Apply the sealant on your rolling kit as a primer before rolling it out onto your pavers. To ensure that you can apply enough sealant as you go, make sure there is always a good pool of sealant in front of your roller. Don’t worry if it takes a while to cover the entire area because sealant coverage is typically poor on the first coat.
Step 4 – Apply the First Coat of Sealing
Now, apply the first coat of paver sealant on the surface of your block pavers. But before you start, you should take safety precautions and make sure the area is well-ventilated. Now, start applying the first layer of sealant. Avoid applying a thick layer of sealant on the surface. Once you’ve applied, leave it to dry for around 1-2 hours.
Step 5 – Apply the Second Coat of Sealing
Once the first coat is dry, apply a second coat of sealing. Fill the paver sealant in a sprayer and apply the second coat on the surface of your block pavers. Make sure to cover the entire surface. Once you’ve applied the second layer of paver sealant, leave it to dry for around 24 hours before you start walking or driving on the surface.
